Java project in subdirectory of workspace

Hello,

I'm in the same situation as https://github.com/microsoft/vscode-java-dependency/issues/493 and would like to understand how things are supposed to be configured.

I'm having a folder structure like

my-project/ (workspace)
 L java-app/
   L pom.xml
 L frontend/
 L some-other-sub-project/
 L my-project.code-workspace

My workspace file looks like

{
	"folders": [
		{
			"path": "."
		}
	],
	"launch": {
		"configurations": [
			{
				"type": "java",
				"name": "Launch My project java app",
				"request": "launch",
				"mainClass": "com.example.javaApp.MainClass"
				"envFile": "${workspaceFolder}/.env",
				"projectName": "java-app",
				"args": "--spring.profiles.active=development"
			}
		],
		"compounds": []
	}
}

But

• the "Java Projects" section in the explorer is empty
• when running my launch config I'm getting

  ConfigError: The project 'newstimeline-server' is not a valid java project.

When I change my workspace to

	"folders": [
		{
			"path": "."
		},
                {
			"path": "java-app"
		},
	],

then my project is shown in the "Java Projects" section and I can get the launch config to somehow work.
But that seems more like a workaround.

How would the java extension pack expect me to configure this situation?

Reproduisez la disposition du workspace signalée avec java-app/pom.xml et la configuration de lancement .code-workspace fournie. Commencez par étudier la manière dont l’extension Java découvre les projets dans des dossiers de workspace imbriqués et résout projectName. C’est terminé lorsque la vue Java Projects reconnaît le projet imbriqué sans ajouter java-app comme dossier de workspace séparé, et que la configuration de lancement fonctionne de manière cohérente.
